Arrange the following compounds in increasing order of boiling point. Propan- 1-ol. butan-l-ol. butan-2-ol. pentan- 1-ol

I. Propan- 1-ol. butan-2-ol. butan- 1-ol. pentan- 1-ol

II. Propan- 1 -ol. butan- 1 -ol. butan-2-ol. pentan- 1 -ol 

III. Pentan-l-ol. butan-2-ol. butan- 1 -ol. propan- 1-ol

IV. Pentan-l-ol. butan- 1-ol. butan-2-ol. propan- 1-ol 

This is a multiple choice answer as classified in NCERT Exemplar

(I) Propan- 1-ol. butan-2-ol. butan- 1-ol. pentan- 1-ol 

The compounds Propan-l-ol, butan-2-ol, butan-1-ol, pentan-1-ol belong to the alcohol family. The structure of the given  alcohols are as shown below:

With increase in the molecular weight, the boiling points of alcohols increase. Hence, butan-1-ol has higher boiling point than propan-1-ol. Similarly, pentan-1-ol has higher boiling point than butan-1-ol.

Hence, the increasing order of the boiling points of alcohols is propan-1-ol < butan-1-ol < pentan-1-ol.

With increase in the branching of alkyl groups, the boiling point of alcohols dec

Hence, the increasing order of the boiling points of alcohols is propan-1-ol < butan-1-ol < pentan-1-ol.

With increase in the branching of alkyl groups, the boiling point of alcohols decreases. Thus, butan-2-ol has lower boiling point than butan-1-ol. The increasing order of the boiling points of given alcohols is
